I have had it for three weeks and like it a lot. The production is good in my 30G but the noise is average.
if you do get it and set is up it will start to produce little bubbles in your tank they will go away in a couple days and then start to work great.
i got mine for 45 bucks and of course it was worth every penny
my lfs said they are a japanese company and not to well known yet but he keeps half his stuff on the jebo skimmers
